Run 2 Lab Report
The mechanism that is compatible with the rate law that is calculated is rate=k[I−][S2O8^2-], which matches with the b) mechanism. It starts with the slow step, which is the rate determining step and it also states that the rate law equals to rate=k[I−][S2O8^2-]. The average reaction time for Run 2 without catalysis was 73.68s and with catalyst was 12.13s, which have a big difference, the average reaction time for Run 2 with he catalyst was much faster than the one without the catalyst. Based on the result of average reaction time, the catalyst helps reaction to increase the rate of the reaction. Collision theory states that the particles in the reaction should collide with a certain minimum energy, which is called the activation energy. If

881 Words | 4 PagesNevertheless, the effects caused by the breakage of bonds will eventually lead to a decrease in the rate of reaction. As seen in the data, the reaction rate increased from 0.088 to 0.101 throughout the interval of -5℃ to 20℃ then decreased to 0.037 throughout the interval 20℃ to 56℃. This can be explained by the fact that 20℃ is the optimal temperature, therefore the active site of the enzyme is complementary to the substrate, causing the rate of reaction to be

Lab Report Chemistry Lab
728 Words | 3 PagesThe lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.
Blast Off Lab Report
407 Words | 2 PagesIn the “Blast Off” lab, we had launched a foam rocket into the air by pumping air into a nozzle, shooting the rocket up, and then recording the time from launch to when it hit the ground. I have learned and now understand the mechanics of kinetic and potential energy. The experiment I had conducted relates to energy in that as we observed the rocket, its energy was constantly transforming as it was in motion. Kinetic energy is an object’s energy based on its motion. Potential energy is energy based on an object’s shape or position.
Group 1 Lab Report
1195 Words | 5 PagesGroup 1: All the elements that were tested from group 1 had a pH level of 12. This meant that all the tested elements produce an alkaline solution. Group one elements readily lose their valence electron as they wish to form a full valence shell this gives them all a low electron affinity. The group one elements have different electronegativity going down the group. Electronegativity of the elements decreases with the increasing the atomic radii.

1090 Words | 5 PagesIt was hypothesized that the optimal pH for the enzyme was pH 7 while the 1.0 ml peroxidase would have the best reaction rate. At the end of the experiment the results prove the hypothesis to be incorrect. INTRODUCTION Enzymes are proteins that allow a reaction to speed up. These proteins are made up of monomers known as amino acids.

1117 Words | 5 PagesThe effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.

781 Words | 4 PagesEnzyme with the least extract, 0.5mL, had the lowest absorption rate at the end. However, it had a higher rate than 1 ml ones until 80 seconds passed. I assume that decrease of the absorbance rate as it is fully saturated and cannot absorb more like other two controlled enzymes with larger amounts of extracts. According to the figure 2, reaction rates and concentration of enzyme extracts are directly related. As the amount of extract increases, the reaction rate also increases constantly.
12U Biology Lab Report
560 Words | 3 PagesThroughout 12U Biology this year we have learned about many different enzymes and proteins which both humans and plants possess. This piece of writing's purpose is to touch on 3 plant hormones which we do not touch on and to explain how the hormones carry out their specific actions. The three hormones that are going to be covered are cytokinin, abscisic acid, and brassinosteroids. To begin, what do cytokinins do in a plant? cytokinins were found in the late 1950s by F. Skoog and C.Miller, and what they found was that cytokinins influenced cell division in plants.
Microbe 3c Lab Report Procedure
389 Words | 2 PagesAnalysis of Major Unknown 3C Summary: A series of tests was done with Microbe 3C. A Gram stain was done and the sample was gram positive. A streak plate was completed revealing that the microbe was clear/white in color, margin was entire, shape was circular, elevation was convex/raised, and the opacity was translucent. The last test done was the sucrose test.

Common dietary foods consumed by birds were substituted for toothpicks and beans. Hypothesis: In the valley were the toothpicks are found, the tweezer beaked bird will be the most affective at collecting food. This is due to the toothpicks resembling that of worms.
E Colo Lab Report
830 Words | 4 PagesMechanistically, DNA replication in eukaryotic organisms is similar in prokaryotic organisms. Before I examine their differences, I will first describe the general steps to replicate the DNA of E. coli. Scientists have gained much insight into DNA replication by studying this particular bacterium. Unlike eukaryotes with linear chromosomes, E. coli’s chromosome is circular.
Effect Of Enzyme Concentration On Enzyme Reaction
1046 Words | 5 PagesThey can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.
